To all whom it may concern;

Be it known that I, SYLvEs En C. DE

FORE, a citizen of the UnitedStates, residing at Kansas City, in the county of Jackson and [State of-Missouri, have invented certain new and useful Improvements in SpeedIndicatingApparatus and I .do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled My invention relates to a speed indicating apparatus, and more particularly to an apparatus of that class for use with automo- My present invention being an improvement on the apparatus shown and described in my application for Letters Patent filed November 13, 1906, Serial No. 343,272.

It is the object of my invention to provide an apparatus which is so arranged and con- .eature of the means fo'r'closing a circuit toexcite the indicator when the speed for which the device is' set has been reached. In accomplishing nectedwith the running gearor other parts of a vehicle such as. an automobile, that a signalor indicator may be operated should the vehicle attain a certain speed, which is previously determined by regulation of a ortion of-the apparatus. The. principal present invention being the this object, I have provided the improved details of structure whichv will presently be fully described and pointed. out in the claims, reference being had to the accomplanying drawings forming art of this speci cation, in which like re erence numerals refer to like parts, and in which,'

Figure Iisa view in elevation of the rear of the dash-board of an automobile, carrying the box inwhich a portion-of the indicating.

apparatus is located,-together with a portion 0 the front running gear, withparts con-.

.necting same with the indicator. 7 Fig. II is 1 a similar viewlof the inclosing box andjcon- I tents, the former being-in vertical section Fig. 111 is an enlarged detail view in elevationof a portion of the governor shaft show ing the collar carryingdihe upper governor arm.-

Fig. IV is an" enlarged detail view'ofthejoint onwhich'the indicator shaft is sup-' ported.

.by and revolving in a bearing 7, supported.

by a standard 8, the lower end of which standard is enlarged to form a ball 9, and is seated in a pocket in a flange 10. Flange 1O is rigidly secured to axle 1, and has a cap 11, threaded on its upper end, which covers the.

pocket, but is'provided with a central perforation 12, through which the standard 8 projects.

Secured to shaft 6 is a flexibleshaft 6, which extends to and is rigidly connected with the shank 13 of a collar 14, which collar is supported by and revolubly mounted in the bottom of a box 15 carried by the dashboard 16 of the vehicle. Rigidly secured to collar 14 is the lower cross bar 17 of'a governor comprising thev arms 18 and balls 19, the former of which are pivotedto the lower bar 17 and an upper bar 20, which latter is-reVolubly mounted 'in a groove in -a collar 21, carried by'a shaft 22, the lower end of which shaft is revolubly seated in a pocket in bar 17 -while its upper end is keyed in a bracket 23 carried in the top of box 15.

The upper part of shaft 22 is referably squared and collar 21 rovide'd wit a square perforation through w ich the shaft extends, so that the collar is prevented-from revolution thereon. The lower end ofshaft 22 isrounded so that it may set in the pocket in v the bar 17, and will [permit the revolution of said bar therearoun On-collar 21 1s an arm 24 which extends outwardly almost to the side of box 15,'and. carries near its end a co Secured'to the side of arm 24 is a bracket 26 in which is adjustably secured in line with stud25, a co per orflike plug 27, the latter being preferably threaded and secured in'bracket 26 by means of nuts 28 and 29 so that when desired, the plug may be turned forward or back to bring it nearer or further from the plug on arm 24. Secured in a suitable manner, adjacent to box 15 is a box 30, containing a battery and also secured per or. like plug 25. ox 15, in line. withadjacent to box'15 is an indicating device of 1 10 the spring 35.

asuitable nature, in this case shown to be a I I claim as new therein, and desire to secure bell 31. ,32 is a coil connecting stud 27 with l the-battery, 33 is a coil connecting the indicating device and battery and 34 is a coil connecting the indicating device and stud'25..

35 is a spring surrounding shaft 22 and tending to yieldingly spread the governor arms lon 'tudinally.

hen'in use the parts are assembled in the manner described, and the stud 27, which i has been marked to indicate various speeds,

by Letters Patent is,

1. In a-speed indicating apparatus, the

combination with an indicating device, of a governor'mechanism comprising a pair of jointed arms carrying weights, a base con- Igrooved collar carried by said shaft, and

is set for the desired speed, the marking of the stud being made according to the strength of 5 When the vehicle is travelspur wheel on its hub around therewith, 1

which wheel meshing with the small wheel on shaft 6, will cause said wheel and shaft to revolve,'thereby revolving the flexible shaft, which is connected with 'the governor. As the speed of the vehicle is increased, the governor will revolve with increased rapidity, the Weight of the balls spreading the governor arms, and drawing the upper collar downwardly against the tension of spring 35, the lower end of the governor being anchored against vertical movement by shaft 22. As the vehicle travels, the governor will be revolved and as the speed is increased, the in creased rapidity of revolution of the governor will spread its arms outwardly, drawing the upper cross arm downwardly so that when the speed for which the device has been set has been attained, the plug 25 will have been carried down into contact with plug 27, completing acircuit through the indicating device, and operating the indicator which in this case would bethe ringing of hell 31; when the driver will be warned of the speed at which he was traveling, and may, if desired, reduce the speed.

My a 'aratus is especially useful in cit es or locahties having-laws or ordinances hnnting speed at which'a vehicle may travel.

Having thus described myinvention, what adapted for longitudinal but not for rotary movement, an arm connecting the other ends of said governor arms and adapted for revolution in the groove in said collar, a circuit terminal carried by said collar, a second terminal adjacent to and adapted for contact with said first terminal, and means for revolving said governor mechanism.

2. In a speed indicating. apparatus, the combination with an indicating device, of a governor mechanism comprising a pair of jointed arms carrying weights, a base connecting the arms of said mechanism at one end, and having a recess in its inner-surface, a shaft rigidly mounted at one end'and having its loose end seated in said recess, a grooved collar carried by said shaft, and adapted for longitudinal but not for rotary movement, an arm connecting the other ends of said governor arms and adapted for revolution in the groove in said collar, a circuit terminal carried by said collar, a second terminal adjacent to and adapted for contact with said first terminal, means for adjusting said stationary terminal, a connection between each of said terminals and the indicating device, and means for revolving said governor mechanism.

In testimony whereof I afliX my signature in presence of two witnesses.
